Integrating Robotics into First-Year Experience Courses Tyson S. Hall1 and P. Willard Munger2 Abstract – Robotics are a popular component of many introductory engineering and computer science courses. At Southern Adventist University, the School of Computing faculty decided to integrate robotics into a discipline- specific section of the University’s first-year experience course. The integration of robotics into a first-year experience course has created a hands-on introduction to college life within the Computing discipline while introducing students to the problem-solving process. This paper will introduce a very low-cost robotic platform kit ($50-75) that has been developed for the first-year experience course. Student assessment data from the first offering of this course with the SouthernBot 2.0 kit shows that overall, students were engaged in the open-ended design projects completed during the building of the robot platform. Keywords: robotics, first-year experience, freshman experience. INTRODUCTION At Southern Adventist University, the first-year experience course is a one semester hour discipline-specific course that provides students with a roughly equal mix of general education content and discipline-specific content. This provided an opportunity within the School of Computing to include a small freshman design experience within the first-year experience course. This experience is designed to engage students in the basic problem-solving processes that are prevalent in computer science and engineering and introduce them to basic skills such as soldering, printed circuit board (PCB) design and simple programming logic. Over the three years that the authors have taught the first-year experience course in the School of Computing, various robot systems (including LEGO MINDSTORMS NXT and iRobot Create) and projects have been used to engage the students in the problem-solving process and to excite students in their choice of a STEM career. Based on student feedback from previous classes, a new custom robot platform has been designed and distributed to students in kit form. Building a robot from a kit exposes students to the mechanical, electronic, and software aspects of the design process. In addition, the robot has been designed to be affordable ($50-75) so students can purchase them from the campus bookstore in lieu of a textbook. Providing each student with his/her own robot platform allows them to experiment with the robot outside of class and even after the semester is over. This is an important characteristic of the robot platform described in this paper, because as shown in one study, student performance can actually decline in programming classes that utilize classroom-based robots that are not available to students outside of class/lab periods [6]. Commercial platforms tend to be quite robust and easily available; however, their costs range from $150-300, which can still be rather prohibitive for students to purchase their own personal robot for an entry-level class. Robotics have become a popular addition to introductory engineering and computer science courses because of their physical embodiment of the computing process and their ability to motivate students to learn computing principles [8, 9, 11, 13]. Many courses make use of commercially available platforms such as LEGO MINDSTORM [4, 5, 8, 10, 15], iRobot Create [14], Scribbler [1], TekBot [7], and Parallax Boe-bot [3], while a few courses use special- 1 Southern Adventist University, Collegedale, TN 37315-0370, [email protected] 2 Southern Adventist University, Collegedale, TN 37315-0370, [email protected] 2011 ASEE Southeast Section Conference purpose kits [2]. Each of these robotic platforms have advantages and disadvantages including more or less flexibility, robustness and community and textbook support [12]. This paper overviews the design of a new inexpensive robot platform for first-year experience courses and the curriculum that is used for the first-year experience course at Southern Adventist University. It also reports on lessons learned from the first use of these robots in the first-year experience course and show results from an assessment of student attitudes regarding the robot project and their engagement in the course. SOUTHERN CONNECTIONS Southern Adventist University (Southern) is a private, accredited, co-educational institution offering masters, baccalaureate, and associate degrees. The student body is approximately 3000 students with a variety of religious backgrounds although ninety-four percent are Seventh-day Adventists. Southern is located in southeast Tennessee just east of Chattanooga. Southern has a 95-year history of liberal arts education. Although sixty percent of students on Southern’s campus today major in areas other than those considered as liberal arts, this heritage is seen in the strong general education requirements still maintained by the university. Computer science and embedded systems students are required to complete 43 semester hours of general education courses in addition to their major and cognate courses. Through the general education program, students receive a broad foundation in communication, history, religion, literature, and psychology. In 2006 Southern Adventist University initiated their first-year experience course entitled Southern Connections that meets 17 times during the semester (including extended sessions during orientation the week before school starts and a final exam period during exam week). The approximately 40 sections of this course are overseen by a first- year experience coordinator at the University level; however, the sections are implemented within each department and taught by faculty within each department. This loosely centralized structure provides for some common content across the sections while allowing the individual departments to customize the course to be more suited to students in their disciplines. As shown in Fig. 1, the official course description for this course allows for this flexibility. Official Course Description: “This seminar is designed to equip first-year students for success in the university environment. Emphasis will be placed on the development of critical and creative thinking skills within a student’s area of interest.” Modified Course Description in the School of Computing “A hands-on introduction to problem solving using computing technologies. Students will design and assemble printed circuit boards and program robots to achieve different missions with emphasis placed on problem solving and the team design process including project/time management, team management, hardware design, implementation, software development, testing, analysis, and documentation. Throughout the semester, students will learn valuable skills including note-taking, time management, test-taking strategies, soldering, problem solving, and real-time programming strategies.” Figure 1. The official course description for Southern Connections provides for flexibility in the content and method of pedagogy within each section. The modified course description for the Southern Connections section within the School of Computing reflects the emphasis put on the scientific/engineering process through hands-on problem-solving experiences in this section. In the School of Computing’s Southern Connection section, emphasis is put on hands-on experiences including soldering circuit boards, designing printed circuit board schematics and layouts, assembling custom robot structures, and programming basic autonomous robot functionality. This section uses a top-down methodology where students are introduced to larger systems then they can fully comprehend and then given just enough knowledge about the system to complete some basic tasks. This methodology allows students to experience the computer science discipline early in their university career and seeks to motivate their continued study in this discipline. Based on 2011 ASEE Southeast Section Conference student feedback from earlier offerings of this course, the instructors have increased the amount of lab/hands-on activities in this course and decreased the amount of traditional lectures. In addition, the hands-on activities have been distributed throughout the semester more evenly with the lecture content to keep student interest high throughout the semester. As shown in Fig. 1, the modified course description for the School of Computing’s section of Southern Connections is quite aggressive in its content coverage. Most of these topics are introduced very briefly in lecture

  • An Introduction to the NASA Robotics Alliance Cadets Program
    Session F An Introduction to the NASA Robotics Alliance Cadets Program David R. Schneider, Clare van den Blink NASA, DAVANNE, & Cornell University / Cornell University CIT [email protected], [email protected] Abstract The 2006 report National Defense Education and Innovation Initiative highlighted this nation’s growing need to revitalize undergraduate STEM education. In response, NASA has partnered with the DAVANNE Corporation to create the NASA Robotics Alliance Cadets Program to develop innovative, highly integrated and interactive curriculum to redesign the first two years of Mechanical Engineering, Electrical Engineering and Computer Science. This paper introduces the NASA Cadets Program and provides insight into the skill areas targeted by the program as well as the assessment methodology for determining the program’s effectiveness. The paper also offers a brief discussion on the capabilities of the program’s robotic platform and a justification for its design into the program. As an example of the integration of the robotic platform with the program’s methodologies, this paper concludes by outlining one of the first educational experiments of NASA Cadets Program at Cornell University to be implemented in the Spring 2007 semester. I. Introduction To be an engineer is to be a designer, a creator of new technology, and the everyday hero that solves society’s problems through innovative methods and products by making ideas become a reality. However, the opportunity to truly explore these key concepts of being an engineer are often withheld from most incoming engineering students until at least their junior year causing many new students to lose motivation and potentially leave the program.

  • The Impact of Robot Projects on Girl's Attitudes Toward Science And
    2007 RSS Robotics in Education Workshop The Impact of Robot Projects on Girl’s Attitudes Toward Science and Engineering Jerry B. Weinberg+, Jonathan C. Pettibone+, Susan L. Thomas+, Mary L. Stephen*, and Cathryne Stein‡ +Southern Illinois University Edwardsville *Saint Louis University, Reinert Center for Teaching Excellence ‡KISS Institute for Practical Robotics Introduction The gender gap in engineering, science, and technology has been well documented [e.g., 1, 2], and a variety of programs at the k-12 level have been created with the intent of both increasing girl’s interest in these areas and their consideration of them for careers [e.g., 3, 4, 5]. With the development of robotics platforms that are both accessible for k-12 students and reasonably affordable, robotics projects have become a focus for these programs [e.g., 6, 7, 8]. While there is evidence that shows robotics projects are engaging educational tools [8, 9], a question that remains open is how effective they are in reducing the gender gap. Over the past year, an in-depth study of participants in a robotics educational program was conducted to determine if such programs have a positive impact on girls’ self-perception of their achievement in science, technology, engineering, and math areas (STEM), and whether this translates into career choices. To examine social and cultural issues, this study applied a long-standing model in motivation theory, Wigfield and Eccles’s [10] expectancy-value theory, to examine a variety of factors that surround girls’ perceptions of their achievement. Expectancy-value theory considers that individuals’ choices are directly related to their “belief about how well they will do on an activity and the extent to which they value the activity” [5, p.

Introduction Koreans occasionally introduce their country with phrases like, ‘The best internet penetration in the world’, or ‘internet power’. A huge infra-structure for the internet has been built in recent years. The internet is becoming a general tool for anyone to exploit anytime and anywhere. Additionally, concern about the silver industry, which is related to the life of elderly people, has increased continuously by extending the average life span. In this respect, application of robots also has increased concern about advantages of autonomous robots such as convenience of robots or help from autonomous robots. This increase in concern has caused companies to launch products containing built-in intelligent environments and many research institutes have increased studies on home automation projects. In this book chapter, we address autonomous systems by designing fusion systems including intelligent mobility and home automation. We created home oriented robots which can be used in a real home environment and developed user friendly external design of robots to enhance user convenience. We feel we have solved some difficulties of the real home environment by fusing PDA based systems and home servers.

The paper introduces and compares the use of current robotics kits developed by different companies in Japan for education purposes. These kits are targeted to a large audience: from primary school students, to university students and also up to adult lifelong learning. We selected company and kits that are most successful in the Japanese market. Unfortunately, most information regarding the technical specifications, the practical usages, and the actual educational activities carried out with these kits are currently available in Japanese only. The main motivation behind this paper is to give non-Japanese speakers interested in educational robotics an overview of the use of educational kits in Japan. The paper is completed by a short description of a new pseudo-natural language we propose for effectively programming one of the presented robots, the educational humanoid Robovie-X. Keywords: educational robot kits, humanoid robots, wheeled robots, education Introduction With the advance of technology, robotics have been successfully used and integrated into different sectors of our life. Industrial robot arms almost completely replaced the manual workload. Service robots, such as Roomba, serve as home helpers in the households, dusting the house automatically. Also in the field of entertainment, many robots have also been developed, the robot dog AIBO provides a successful example of this.

Abstract This study addresses the issue of using robotics in K-12 STEM education. The authors applied intrinsic motivation theory to measure participant perceptions during a series of robotic workshops for K-12 students at Purdue University. A robotic excavator arm using fluid power components was developed and tested as a tool to generate interest in STEM careers. Eighteen workshops were held with a total number of 451 participants. Immediately after the workshop, participants were provided with a questionnaire that included both quantitative and qualitative questions. Fourteen of the questions are quantitative, where a participant would characterize their after-workshop experience using a 1 to 7- Likert scale. According to the intrinsic motivation theory it was hypothesized that participant perceptions should differ depending on their gender, race, and age.

  • The Robotics and Mechatronics Kit “Qfix”
    The Robotics and Mechatronics Kit “qfix” Stefan Enderle Neural Information Processing Department University of Ulm, Germany [email protected] Abstract. Robot building projects are increasingly used in schools and universities to raise the interest of students in technical subjects. They can especially be used to teach the three mechatronics areas at the same time: mechanics, electronics, and software. However, it is hard to find reusable, robust, modular and cost-effective robot development kits in the market. Here, we present qfix, a modular construction kit for edu- tainment robotics and mechatronics experiments which fulfills all of the above requirements and receives strong interest from schools and univer- sities. The outstanding advantages of this kit family are the solid alu- minium elements, the modular controller boards, and the programming tools which reach from an easy-to-use graphical programming environ- ment to a powerful C++ library for the GNU compiler collection. 1 Introduction Robot building projects are a good means to bring the interesting field of robotics to schools, high-schools, and universities. Studying robotics the students learn a lot about mechanics, electronics, and software engineering. Additionally, they can be highly motivated and learn to work in a team. Performing a lot of robot building labs with pupils and students, we found that there is a gap between the relatively cheap toy-like kits, like LEGO Mind- storms or Fischertechnik Robotics and the quite expensive off-the-shelf robots. The toy kits offer a good opportunity to start building robots, but they mostly support the control of only 2 or 3 motors and the same number of sensors.
